Single transmitting-receiving array includes the 302 and the 12nd probe 303 of the 301, the 11st probe of the tenth probe being arranged from front to back,
The 301 and the 11st probe 302 of tenth probe is 70 ° of probes, and single transmitting-receiving chip with backward launched ultrasonic wave is used for
Rail head of rail position is detected, can find the defect of vertical direction or low-angle, the 12nd probe 303 is 0 ° of probe, tool
Have the single transmitting-receiving chip for emitting ultrasonic wave straight down, for detecting steel rail web, it can be found that the crackle of horizontal direction or
Defect.
In the defectoscope, controller 402 is set to 401 top of water tank, and vibration damping is equipped between controller 402 and water tank 401
Bracket 403 can reduce vibration of the controller 402 in defectoscope traveling process by the setting of damping frame 403.
Ultrasonic probe is installed below roll-out tray by crash-proof bracket 404.
Existing flaw detection trolley is all the probe holder of unidirectional anticollision, will not be damaged to probe during advance, but
It is in reversing, the rail level for meeting out-of-flatness will collide probe, gently then miscue probe, influence the coupling of probe, heavy then general
Probe is knocked or is broken, and directly affects flaw detection process.Therefore two-way crash-proof bracket 404 is used in this defectoscope.
As shown in Figure 7 and Figure 8, specific crash-proof bracket 404 includes the lower frame 2 of upper frame 1, connection ultrasonic probe, with
And the upper frame 3 for connecting lower frame 2 with upper frame 1, the probe holder further include promoting lower frame 2 and upper frame 3 multiple after exercise
The first torsionspring 4 and the second torsionspring 5 of position.Below in the introduction of probe holder specific structure, " clockwise ", " inverse time
The description that needle " is carried out with the angle of Fig. 7.
Upper frame 1 is arranged along the direction of guide rail, has horizontal lower leading face, in setting respectively in the left and right sides of upper frame 1
There are a locating shaft 11 and a connecting shaft 12.
Lower frame 2 is turned forward setting on the basis of its bottom, is had at the top of two lower vertical plates and the lower vertical plates of connection two
Lower cross plate, the upper level between two lower vertical plates are equipped with the first axle body 21, the both ends of the first axle body 21 with it is corresponding under
Vertical plate is rotatably connected, and the lower part between two lower vertical plates is equipped with for the clips 22 fixed with ultrasonic probe, under described
Vertical plate is rotatably connected with clips 22, and the lower cross plate is equipped with adjutage, and the adjutage is equipped with and leads under upper frame 1
The idler wheel 23 of row face sliding contact.
Upper frame 3 tilts backwards setting on the basis of its bottom, has in the middle part of two upper vertical plates of two upper vertical plates and connection
Upper cross plate, two upper vertical plates are located at the left and right sides of upper frame 1, and are rotatably connected with upper frame 1 by the second axle body 31, described
Locating shaft 11 can limit corresponding upper vertical plate and rotate clockwise along the second axle body 31, the lower end of the upper vertical plate and the first axle body
21 rotation connections.
First torsionspring 4 is set on the first axle body 21, two spring arm is linked with lower cross plate and upper cross plate respectively, is used
It is resetted after lower frame 2 is rotated clockwise along the first axle body 21.
The setting of limit shaft limits upper frame 3 and rotates clockwise in generation when probe holder works normally, and passes through the
The setting of one torsionspring 4 promotes the upper vertical plate of upper frame 3 and the lower cross plate of lower frame 2 to contact, and forms position limiting structure, limitation
The generation of lower frame 2 rotates counterclockwise, which ensure that the stability of upper and lower frame body 2 state in normal work.
Second torsionspring 5 be set to 12 side of connecting shaft the second axle body 31 on, two spring arm respectively with connecting shaft
12 and corresponding upper vertical plate link, for limit upper vertical plate along the second axle body 31 rotate counterclockwise after reset.
Cooperation lower frame 2 turns forward the structure feature of setting, so that the front or behind of lower frame 2 encounters barrier
When active force, lower frame 2 all can first generate clockwise movement tendency, and ultrasonic probe is lifted avoiding obstacles, pass through barrier
It is resetted again by the active force of torsionspring after hindering object.
When flaw detection trolley, which travels forward, encounters barrier, lower frame 2 is transmitted by rearward force by the first axle body 21
To the lower end of upper frame 3, since the upper end of upper frame 3 cannot be rotated by the limitation of locating shaft 11 clockwise about the second axle body 31, institute
It is fixed with upper frame 3, and lower frame 2 is rotated clockwise around the first axle body 21, and makes 4 accumulation of energy of the first torsionspring simultaneously,
After lower frame 2, which lifts ultrasonic probe, to clear the jumps, under the effect of the first torsionspring 4, lower frame 2 is around the first axle body
21 counterclockwise movements are reset to probe contacts to rail surface.To restore the normal operating conditions of probe holder, so that ultrasonic wave is visited
It is nose heave newly with rail face contact.
When flaw detection trolley moves backward encounters barrier, lower frame 2 is mobile by reaction force forward upward, due to being pushed up
The compacting of frame 1,3 pulling force effect of upper frame and barrier reaction force so that 3 lower end of upper frame be lifted up it is inverse around the second axle body 31
Hour hands rotation, since the first axle body 21 increases, and idler wheel 23 due to by the compacting of upper frame 1 can only forward slip, while 2 edge of lower frame
The first axle body 21 rotates clockwise, and makes 5 accumulation of energy of the first torsionspring 4 and the second torsionspring, when lower frame 2 visits ultrasonic wave
After head is lifted and cleared the jumps, since the torque of the second torsionspring 5 is greater than the first torsionspring 4, in the second torsionspring 5
Under effect, upper frame 3 resets to upper end against locating shaft 11 around 31 clockwise movement of the second axle body, and upper frame 3 stops operating,
First torsionspring 4 effect under, lower frame 2 around 21 counterclockwise movement of the first axle body be reset to ultrasonic probe again with rail surface
Contact, to restore the normal operating conditions of probe holder.
The probe holder is designed using way anti-collision, and the direct hardness for reducing probe and rail level is hit, and is effectively extended
The service life of probe, and reduce hardware fault, improve the working efficiency of flaw detection.
Wherein, two spring arms of the first torsionspring 4 are reported to the leadship after accomplishing a task setting, enhance reset of first torsionspring 4 to lower frame 2
Active force, and lower frame 2 can be made to be bonded limit with upper frame 3, guarantee the stability of the probe holder working condition.
It is equipped with the limit baffle 32 of limitation the second torsionspring 5 axial movement in the outer end of the second axle body 31, to prevent the
Two torsionsprings 5 are detached from from the second axle body 31.And a circle groove, corresponding second torsionspring are equipped in connecting shaft 12
5 spring arm is in the groove, to guarantee the stability of 5 hook joint position of the second torsionspring.
The above is only the preferred embodiments of the utility model, anyone content according to the present utility model is to the utility model
A little simple modification, deformation and the equivalent replacement made each falls within the protection scope of the utility model.
